Accident research

GIDAS A successful project for the benefit of traffic safety

Accident research has contributed significantly to traffic safety improvements. GIDAS captures and thoroughly analyses around 2,000 accident data per year. The findings of these studies are integrated directly into automotive engineering, test procedures and other traffic safety sectors.

Three areas are generally critical when analysing an accident for the accident research: the accident scene, the vehicles and the passengers and/or involved persons.

The "German-In-Depth-Accident-Study” (GIDAS) is the most informative way for capturing accident data. It is a joint project of the Research Association for Automotive Technology (FAT), the Federal Highway Research Institute and the Technical University of Dresden.

Around 2,000 accidents are recorded annually for GIDAS in Hanover and Dresden. 500 to 3,000 individual data are captured per accident, like e.g. road layout, traffic control, crash information, circumstances of the accident and accident causes. This survey is complemented by personal information, like body weight, height, etc. All information is stored in an anonymised form in a database.

The data evaluation enables various applications. The use for the revision of laws, guidelines and standard e.g. allows for an adjustment of the modifications to the actual accident situation. The information also serves to describe suitable test procedures in the context of type approvals. The detailed findings can also help automotive manufacturers to further increase the safety level.

GIDAS can also provide valuable support for positioning traffic signs, poles and the like or even the layout of tree protection systems – for the sake of an ever improving traffic safety.
